In Situ Toxicity Reduction and Food Safety Assessment of Pak Choi ( L.) in Cadmium-Contaminated Soil by Jointly Using Alkaline Passivators and Organic Fertilizer.

An economical and effective method is still lacking for cadmium (Cd) toxicity reduction and food product safety improvement in soil-vegetable systems. Therefore, this study aimed to reduce the Cd toxicity to pak choi ( L.) by jointly using passivators and organic fertilizer, highlighting food products' safety based on pot experiments.

Visual Reasoning: From State to Transformation.

Most existing visual reasoning tasks, such as CLEVR in VQA, ignore an important factor, i.e., transformation.

Exploring the structural regularities in networks.

In this paper, we consider the problem of exploring structural regularities of networks by dividing the nodes of a network into groups such that the members of each group have similar patterns of connections to other groups. Specifically, we propose a general statistical model to describe network structure. In this model, a group is viewed as a hidden or unobserved quantity and it is learned by fitting the observed network data using the expectation-maximization algorithm.
